They said it couldn’t happen. They said wild salmon would never breach penned-up fish farms. They were wrong. And that’s a big problem. On June 11, 2019, members from the ƛaʔuukʷiʔatḥ / Tla-o-qui-aht First Nation, including Tribal Parks Guardians and members of the Clayoquot Sound Indigenous Salmon Alliance, boarded and inspected open net pen […] […]

President Trump’s declaration of a national emergency has escalated tensions all across the southern border. The large majority of residents who live near the Mexican border don’t want the Wall built. Their reasons include fear of the government’s use of eminent domain, the high probability of flooding from a built wall, concern of escalating tensions […] […]

Just when you thought your food choices were clear and safe. UK firm The John Innes Centre has applied for permission to plant experimental genetically modified wheat and broccoli in open fields at their farm outside Norwich, in the United Kingdom. The research company hopes to begin two small-scale field trials in April. In 2017, […]

When you consider our nation’s health, the quality of our food, its decreasing nutritional value and the increased degradation of our farmland, it’s not a pretty picture — and the challenges related to these issues keep growing. By 2050 the world’s population will likely reach close to 9 billion people. To feed everyone, we’ll need […]

Solar energy is an integral part of our renewable energy game plan. Yet as useful as solar is, their efficiency has always seemed incredibly low. Who would consider 15-25 percent “good” if it were your electricity delivery?

Now researchers at the Fraunhofer Institute for Solar Energy Systems ISE, along with Soitec, CEA-Leti and the Helmholtz Center Berlin (Germany) have achieved a new world record for converting sunlight into electricity using a new solar cell structure with four solar subcells. After three years, they have reached new record efficiency of 44.7 percent of solar conversion from ultraviolet through to the infrared, into electrical energy.

Solar subcells that generate 44.7 percent efficiency

“We are incredibly proud of our team which has been working now for three years on this four-junction solar cell,” says Frank Dimroth, Department Head and Project Leader in charge of this development work at Fraunhofer ISE. “This four-junction solar cell contains our collected expertise in this area over many years. Besides improved materials and optimization of the structure, a new procedure called wafer bonding plays a central role. With this technology, we are able to connect two semiconductor crystals, which otherwise cannot be grown on top of each other with high crystal quality. In this way we can produce the optimal semiconductor combination to create the highest efficiency solar cells.”

Could this mean that future solar panels will be miniaturized – and that the need for huge solar arrays will be eliminated? For more on this tantalizing breakthrough, check out http://bit.ly/1frugy5.
